**Proof Strategies in Geometry**

- Make a game plan.
- Make up numbers for segments and angles.
- Look for congruent triangles (and keep CPCTC in mind).
- Try to find isosceles triangles.
- Look for parallel lines.
- Look for radii and draw more radii.
- Use all the givens.
- Check your if-then logic.

## What are the 3 Proofs in geometry?

Two-column, paragraph, and flowchart proofs are three of the most common geometric proofs. They each offer different ways of organizing reasons and statements so that each proof can be easily explained.

## What is geometric proof?

A geometric proof is a deduction reached using known facts such as axioms, postulates, lemmas, etc. with a series of logical statements. While proving any geometric proof statements are listed with the supporting reasons.

## How many proofs are there in geometry?

Geometric Proof There are two major types of proofs: direct proofs and indirect proofs.

## Are geometry proofs necessary?

Geometrical proofs offer students a clear introduction to logical arguments, which is central to all mathematics. They show the exact relationship between reason and equations. More so, since geometry deals with shapes and figures, it opens the student’s brains to visualizing what must be proven.

## What are the main parts of a proof in geometry?

The most common form of explicit proof in highschool geometry is a two column proof consists of five parts: the given, the proposition, the statement column, the reason column, and the diagram (if one is given).

## How do you do proofs in geometry easy?

Practicing these strategies will help you write geometry proofs easily in no time:

- Make a game plan.
- Make up numbers for segments and angles.
- Look for congruent triangles (and keep CPCTC in mind).
- Try to find isosceles triangles.
- Look for parallel lines.
- Look for radii and draw more radii.
- Use all the givens.
